Abstract: ABSTRACT OF THE DISCLOSURE         A programming device having one or more pairs of elec-trical contacts, adapted to be closed and opened at predetermined intervals to control the programme and having a contact control mechanism movable between two stationary positions namely a high position and a low position, the high position corresponding for example to a first position of a contact, and the low position corresponding to a second position of a contact, and further having control operating means, reciprocably movable to and fro along a predetermined path, each such complete reciprocal movement procur-ing a movement of said contact control means from its high to its low position, or from its low to its high position, alternately in sequence and further having a movable programme recording mem-ber, adapted to be provided with a series of standard indicia, said indicia passing in sequence past said control operating means, whereby upon the passage of each said indicia, said control operating means completes one said reciprocal movement for each said indicia, which complete reciprocal movement is thus responsible for procuring either a single closing or a single opening movement of a contact, the contact then remaining so closed or opened until the next indicia operates the control operating means.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a window assembly in which the window units may be removed and which incorporates safety features to prevent the accidental removal of the window unit.  The construction of the window assembly is such that sash members and the window frame  have interlocking flanges which require careful manipulation with respect to one another in order to release the window units from the window frame.           The upper and lower sash members have flanges projecting out-wardly therefrom in an overlapping relationship with respect to corresponding flanges formed in the header and sill whereby in order to remove the window units the lower sash member of each unit must be moved upwardly by a predetermined amount in order to release it for lateral movement with respect to the sill, whereupon the lower sash member of that unit may be moved laterally away from its associated sill side wall to withdraw its locking flange from its underlying relationship with respect to its associated sill flange and thereafter the window unit may be raised until the lower sash member is clear of the sill, whereupon the lower sash member may be moved laterally outwardly over the sill and the upper sash member may be withdrawn from the header by compressing the sash locking member inwardly of the header to release it from the upper  sash member.

Abstract: ABSTRACT OF THE DISCLOSURE     A rotary plug valve having a plug member rotatable in a valve housing member between an open position and a closed po-sition, the plug member carrying a sealing ring, such as an O-ring seal or the like, in a groove provided on its surface between its port openings, the O-ring seal being adapted to encircle one of the ports of the housing member when the plug member is in the closed position.  The rotary plug valve is capable of two-way flow therethrough, and this is realized by providing means for equalizing the pressure across the unsupported portion or segment of the O-ring seal when the same is passing across one of the ports of the valve housing.  By such an arrangement, the pressure across the O-ring seal may be equalized in certain situations such as when the plug member is rotated towards and approaches a position for closing the valve and when the plug member is rotat-ed towards and approaches the full open position and this prevents clipping or shearing of the O-ring seal.  This particular arrange-ment of pressure equalizing means for the O-ring seal of the ro-tary plug valve makes the valve capable of two-way flow in that it may be inserted into a fluid pressure line so that the O-ring seal surrounds the upstream port of the housing member when in closed position, or the downstream port of the housing member when in closed position.

Abstract: Abstract of the Disclosure Disclosed is a system for electrostatic spraying of liquids, such as agricultural pesticides, paints and other liquids, which relies on a novel spray nozzle that combines pneumatic atomization and electrostatic induction charging to provide a stream of electro-statically charged fine droplets.  The nozzle uses a low voltage power supply, e.g. a 12 volt battery, electronically raises the voltage to a level in the range of several hundred to several thousand volts, and applies the high voltage to an annular induction electrode which is embedded in the spray nozzle.  The high voltage components are inside the nozzle, which is made of an electrically insulating material to minimize the danger of shock and the possibility of mechanical damage to the high voltage components.  The spray nozzle operates at a relatively low voltage and at a low input power, but provide a droplet stream at a high droplet charging level, for effective and uniform deposition of the sprayed liquid onto the target.

Abstract: ABSTRACT OF THE DISCLOSURE          A machine tool comprising one or plural storage magazines which are mounted along the vertical direction rotatably around a vertical axis on an upstanding support frame structure at a side of working station.  Each of the magazines stores at the periphery thereof a plurality of spindle heads, workpiece supporting jigs or tool supporting heads which are alternatively set one by one to a set position at the working station for operation on workpieces.  Alternative setting of such heads or jigs is achieved by a selective rotation of each magazine and by a selective lifting and lowering of the head or jig between the set position and a store position just above such set position.  Floor space required for storing and exchanging the heads or jigs is largely saved.  A particular exchanging device for exchanging heads or jigs stored by the magazines for another heads or jigs is provided which greatly enlarges processings possibly carried out at the working station.

Inventor: BENTON CHARLES M
IPC: F23J13/02
Filed: 1977-04-07
Granted: 1980-11-11
Abstract: ABSTRACT OF THE DISCLOSURE A method of prolonging the life of a carbon anode ring furnace is disclosed wherein portions of the confronting refractory brick flue walls of the furnace which have partly collapsed can be readily straightened.  The refractory bricks of the collapsed portion of a flue wall are urged back into the plane of the wall by the method of interposing a hydraulic jack between the closely spaced flue walls and actuating the jack to apply opposing forces to the wall.  The positioning and actuation of the jack is done at a number of locations corresponding to a predetermined circular pattern about a deformation zone to successively reduce the deviation of the bricks of the deformation zone. On reestablishment of the circular pattern with the above method, a tie brick is inserted between the walls to maintain them in their normal spaced relation, prior to removal of the jacking pressures.
